CUSHION-TIRE.

Application led April 6, 1914. A Serial o. 829,834.

To all whom it may concern.'

Be it known that I, SAMUEL Gr. SwENDsoN, citizen of the United States,residing at Topeka, in the county of Shawnee and ntate of Kansas, haveinvented certain new and useful Improvements in Cushion-Tires, of whichthe following lis a specification.

The .present invention relates to certain new and useful improvements incushion tires and has for its object to provide a device of thischaracter in which the resiliency is derived principally from metallicsprings, novel features of construction being involved wherebyV allshocks and jars are effectively absorbed in substantially the samemanner as where pneumatic tires are `employed.

A further object of the invention is to provide a cushion tire which iscomparatively simple and inexpensive in its con` struction, which hasvthe resiliency of a pneumatic tire, which can be quickly placed inposition or removed therefrom, and which is composed of strong anddurable parts adapted to withstand successfully the wear and tear towhich vehicle tires are ordinarily subjected when in use.

f l/Vith these and other objects in view, the invention consists incertain novel combinations and arrangements of the parts as will morefully appear as the description proceeds, the novel features thereofbeing pointed out in the appended claims.

For a full understanding of the invention, reference is to be had to thefollowing d escription and accompanying drawing, in which:-

Figure 1 is a side elevation of a portion of a cushion tire constructedin accordance with the invention, portions thereof being broken away'andshown in section to illustrate more clearly the details of construction.Fig. 2 is an enlarged transverse sectional view through the tire.

Specifically describing the present embodiment of the invention, thenumeral l0 designates the rim or felly of a wheel, and 11 a channelmember which is fitted upon the rim, suitable fastening members such asthe bolts 12b being provided for retaining the channel member inposition. The sides 11"L of the channel member 11 have the outer edgesthereof rabbeted or recessed as indicated at 11b to provide clearancespace for the side flanges 12a of a deformable channel `Specification ofLetters Patent.

tread member 12. vThis tread'member 12 is formed of rubber, acombination of rubber and-canvas, or some other suitable material and isadapted to move in and out radially with respect to the inner channelmember 11 aswell as to deform and give circumferentially to conform tothe surface of the road.

Annular retaining rings 13 are 'tted v-to the side anges l1EL of theinner channel member 11 and project over the rabbeted portions llof the.said side flangesv so as to cooperate therewith to provide annular guidespaces which loosely receive theside flanges l12a of the tread channelmember 12. Suitable fastening means such as the screwslll may be'utilized for retaining the plates 13 in position.

The rubber deformable channel member 12 is reinforced by means of aseries of U- shaped strips or wires 16, the arms ofthe reinforcing wiresextending through the side flanges 19.a of the channel member andterminating in eyes 17 whichproject slightly beyond the flanges andreceive annular wires or tie members 18. These wires 18 are housedwithin the recesses provided by the side plates 13 and serve to drawinwardly upon the side flanges l2a so as to hold the latter against anytendency to soread apart.

Arranged within the channel tread memf ber 12 is a metallic band 19which bears againstthe inner face thereof and is adapted to yield as theouter channel member is deformed. Coilsprings are interposed between theband 19 and-the channel member 11, and in the present instance thesecoil springs are illustrated las arranged in con- The coil springsnormally force the outer deformable channel member 12 away from theinner channel member 11 so as to hold the former yieldablv in operativeposition. As. previously explained, however, the outer channel member 12is adapted to be moved toward and away from the inner channel member11`, and is deformable so as to aocommodate itself to the surface of theroad and thereby obtain a maximum amount of resiliency.

As indicated upon Fig. 1, the sides of the channel shaped rubber treadmember 12 may be provided with a series of slits 30 so that the flangescan be spread apart when assembling the member 12 and before insertingthe wires 18 through the eyes 17 of the U-shaped reinforcing member 16.The band 19 may also have a series of prongs 31 stamped therefrom andbent outwardly so as to engage the rubber tread 12 and prevent creepingor transverse movement thereof upon the band.

Having thus described the invention, what l claim as new and desire tosecure by Letters Patent, is

1. A cushion tire including an inner channel ring, an outer deformablechannel ring, the flanges of the two channel rings having a slidingengagement with each other, U- shaped reinforcements embedded in theouter jchannel ring with the extremities thereof projecting beyond theedges of the flanges thereof, annular tie wires connecting theprojecting extremities of the U- shaped reinforcements and arranged eX-teriorly of the channel ring, and resilient means interposed between thetwo channel rings.

2. A cushion tire including an inner channel ring, an outer deformablechannel ring formed of rubber, the flanges of the two channel ringshaving a sliding engagement with each other, U-shaped reinforcements forthe outer channel ring, annular tie Wires connecting the ends of theU-shaped reinforcements, and resilient means interposed between the twochannel rings.

In testimony whereof I affix my signature in presence of two witnesses.
